<P>PROBLEM TO BE SOLVED: To provide a device for corresponding to instantaneous power interruption, capable of correctly setting instantaneous interruption time. <P>SOLUTION: A cellular phone 1 comprise a battery pack 2, and a device 10 for corresponding to instantaneous power interruption. The device 10 for corresponding to instantaneous power interruption comprises a backup power supply 11 for supplying electric power to an RTC 12 and an instantaneous interruption corresponding section 13 when the supply of the electric power from the battery pack 2 is stopped; the RTC 12 for outputting a clock pulse; and the instantaneous interruption corresponding section 13 having a voltage setting circuit 16 for detecting instantaneous interruption. The voltage setting circuit 16 obtains instantaneous interruption time by the number of pulses in the clock pulse, starts up a power supply again when the instantaneous interruption time is smaller than a threshold value, and keeps a power supply turning off state when the instantaneous interruption time matches with the threshold value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
